I also have problem loading the auth.js and index.js files (example from that book I bought). It works fine in the local network. It acts as if the files are empty. You can see it on my project.
Thank you for your response.

Hola Adrien, respondo 1 año después porque me encontré con el mismo problema. Aprovecho para dejar la solución a futuros programadores.
Debes instalar todos los complementos que indica éste tutorial:
https://randomnerdtutorials.com/esp32-firebase-web-app/
ya que esos pasos no se vuelven a explicar en éste tutorial.

Saludos!

Hi, I had the same problem, for me it was the script tags at the end of the index.html tags, if you have your auth.js and index.js files in the same folder you only need to have “auth.js” and “index.js” as your path in there.

Hi.
Open the javascript console on the web browser and check if you get any errors.

Hi.
For that, you need to know how to make queries.
Here’s the documentation: https://firebase.google.com/docs/reference/js/v8/firebase.database.Query

thank you for excelent tutorial.
I would like to ask how can I set filter for retrieving data from database.
What I need – I save data from two sensors (I add “sensorID” to both of sensors) and than I want to display on web page data from sensor1 or sensor2. Could you help me set filter for sensor1 (or sensor2).
Thank you

Marek
